Java interface example :
In this example i implemented Java shape interface in the circle class .as you will see in the following example ,up-casting for the object "circleshape" .

Note :
In interface :

functions are public and abstract
fields are public and final .

Code:

public class Main {
 
    public static void main(String[] args) {
        
          shape circleshape=new circle();
          
             circleshape.Draw();
    }
}

 interface shape
 {
     public   String baseclass="shape";
     
     public void Draw();
     
 }
 class circle implements shape
 {

    public void Draw() {
        System.out.println("Drawing Circle here");
    }
     
 }
